Release Notes: A modular metric interface for C and Python (DSO support) and scriptable metric module support with Python. All pre-existing metrics (CPU, network, disk, memory, etc.) were converted to metric modules. New metric modules were introduced: multicpu, multidisk, and tcp_conn status. Modular front-end graph support was added. Metric groups that can be viewed or hidden as desired were implemented. Additional scaling capacity was provided for systems with memory greater than 4TB. Native metric support for Windows was improved (Built with CygWin).
Release Notes: Host view metric graphs now work correctly. "Show Hosts" toggled works again. A memory leak in network metrics on Linux has been fixed. A spoof memory leak on gmond has been fixed.
Release Notes: This release fixes a bug that caused XML port output to be truncated, fixes FreeBSD compilation errors, makes gmetad more resilient to round-robin database problems, makes "gmond -t" output more complete, updates the underlying Apache runtime library, expands the maximum size of gmetric messages, provides various minor PHP bugfixes in the Web frontend, and adds 3D pie graph effects.
Release Notes: New AIX metrics code. NetBSD support has been added. It is now possible to specify the PID file with gmond and gmetad. Bugfixes and backwards compatibility support for gmond. Compile fixes for MacOS Tiger. PHP fixes in the Web frontend. Various other bugfixes and code cleanups.
Release Notes: A serious gmond communication bug was fixed, the gmond.conf conversion code was fixed, gmond.conf now allows for include() statements, Linux 2.6.x machines now correctly collect network metrics, and some FreeBSD metric collection bugs were fixed.
Release Notes: Windows support. Gmond can send metrics on multiple unicast and multicast channels. Gmetric parses gmond configuration file to send metrics. Gmond has been completely rewritten to use the Apache Portable Runtime library. IPv6 support has been added for gmond. A new gmond configuration file format allows for complete control over metric collection, access control lists, and bandwidth usage. Solaris gmond properly runs in the background as a non-root user. Mixing operating systems on the same I/O channel is okay now. The XML DTD has been fixed. Darwin support has been updated. A FreeBSD gmond memory leak has been fixed.
Release Notes: This release features a new gmetad cleanup thread that prevents memory leaks in certain cases. Gmetad now also presents a more accurate "TN" in XML streams.
Release Notes: The host DMAX attribute is now honored allowing you to specify a timeout for dead hosts. Ganglia now compiles on 64-bit versions of FreeBSD. A bug has been fixed which caused nodes to falsely be marked as down. An RPM dependency on librrd has been removed.
Release Notes: All standard metrics are now reported on FreeBSD. This release also fixed a bug that allowed a specially crafted UDP packet to cause segfaults in all gmond processes on a multicast channel. The documentation is now included in the distribution as ganglia.html and README.
Release Notes: gmetad is now interactive, allowing for efficient primitive subtree queries of the XML tree. The Web front end has been updated to work with gmetad for very significant speed improvements when loading Ganglia Web pages. gmetad has also been improved to handle clusters with varying clocks (the graph timescales are no longer locked). The time and value thresholds for the gmond network monitors have been increased to prevent unnecessary network traffic. gmond is also more stable and correct on IRIX.
